I was running a NUC+LPS directly into my DAC via ethernet.
I then bought a second hand Antipodes EX for £2,000 (£4,500 new) which acts as a renderer (but can also be roon core and streamer) between the NUC and the DAC. It has 2 ethernet ports so it isolates the DAC from the network switch.
I thought i had taken most of the noise out of the system (Bonn 8 network switch+LPS and a PSM 156 Power conditioner) upgraded fuses and power cables.
The step up in SQ with the EX in the mix, was far more significant than i was expecting.
I recently demoed an EVO 432 server but was not able to hear much difference and certainly, at £5k it was not tempting. The £2k cost of the EX was a bargain and i would have paid well over £5k for this level of improvement.
Good luck.
